Study on the mechanical properties of ABS enhanced by magnesium hydroxide whiskers Yuzhi Jiang Lili Zhang Zhongyang Zhang Lihua Wang School of Materials Science and Engineering, Shenyang Ligong University, Shenyang 110159, China jiangyuzhi136@sina.com Key words: magnesium hydroxide whiskers; ABS; mechanical properties Abstract: The magnesium hydroxide (MH) whiskers/ABS composites were prepared by melt-extrusion with whiskers as fillers.
It is ideal filler for composite materials and metal materials [1].
Magnesium hydroxide whiskers can be used in PE, PVC, PP, and unsaturated polyester as reinforcing materials.
Experiment 2.1 Raw materials The MH whisker was prepared by hydro-thermol method.

The above materials manifest thereat high properties of SME.
The materials, produced in such a manner, in their ultimate states are the last achievement of material science and, undoubtedly, will develop later on.

Test on Corrosion Resistance of GFRP Anchor Bolt Xiaoyong Luo 1, a, Xiexing Tang 1, b, Kailei Li and Yachuan Kuang 1, c 1School of civil engineering, Central South University, Changsha, Hunan, 410083, China atudou0522@163.com, b 106371193@qq.com, cambersonic@gmail.com Keywords: GFRP, Anchor Bolts, Anchoring, Corrosion Resistance Abstract: Steel is commonly used as the materials of anchor bolts in permanent anchoring works.
Steel is generally used as the main materials of anchor bolts in permanent works.
Tests and studies are mainly conducted in advanced countries such as North America, Europe, and Japan, mostly focusing on adhesive property, materials strength and fire resisting performance[7-9,14-15].
Figure 1 Dimensions of GFRP bolt Natural corrosive solutions to the materials mainly include acid, alkalis, sea water and acid rain, etc.
As the time extends, corrosion increases for GFRP bolts in three conditions, 3.2 Weight Change Weight change of GFRP bolts depends on dissolving-out volume of bolt materials, infiltration volume of solution and corrosion products, which, to some extent, present the change of materials property after the GFRP bolts are corroded.

Materials have been sintered for 1 hour at 1760�, 1780� and 1800� under the pressure of 20MPa.
However, the brittle characteristics of SiC such as low strain-to fracture still impose a severe limitation on practical applications of SiC materials.
For these reasons, silicon carbide fiber-reinforced silicon carbide matrix composite (SiCf/SiC composite) is promising for various structural materials, because of their good fracture toughness compared with monolithic ceramic materials.
In the case of 1800�, the materials 2wt% was high hardness, low friction coefficient and wear loss compare with other temperatures and SiO2 contents.

So first, we will introduce what is the circular birefringence of material. 1.2 The concept and the mathematical expression of circular anisotropy In nature, there are many materials with asymmetric structure have anisotropic dielectric permittivity, which causes the optical anisotropy.
Some materials have a special optical properties, their absorption coefficient or refractive index are not the same for left and right circularly polarized lights, which is called as optical circular anisotropic media, also including the circular dichroism and circular birefringence.
For isotropic materials, al=ar and nl=nr.
